Embodiment Construction

[0021] See figure 1 and figure 2 . The hub motor of the present invention includes a hub main body 1 , a rotor disk 2 , a stator 3 and a fixed shaft 4 . The hub main body 1 , the rotor disc 2 and the stator 3 are all of a centrally symmetrical structure, and the fixed shaft 4 is connected to the centers of the hub main body 1 , the rotor disc 2 and the stator 3 . in,

[0022] The hub main body 1 is made of a magnetically conductive metal material, which can be iron, steel, powder alloy, etc., and its external dimensions are determined according to the application occasion and power. Both sides of the hub main body 1 are provided with a first groove 11 for accommodating and fixing a permanent magnet. The first groove 11 is fan-shaped or annular, and its shape corresponds to the shape of the permanent magnet. A permanent magnet 5 is fixed in the first groove 11, and the permanent magnet 5 may be processed from rare earth permanent magnet materials such as NdFeB. Since the ...

Abstract

The invention discloses an energy-saving hub motor comprising a hub, a motor, a fixed shaft, a storage battery, a controller, a rectifying device and a second control switch which is controlled by the controller, wherein the hub and the fixed shaft are rotatablely connected; the motor comprises at least one first stator, a second stator and at least one rotor corresponding to the stators; the stators are fixedly connected with the fixed shaft; the stators comprise stator racks and coil windings which are fixed on the stator racks; the stator racks are fixedly connected with the fixed shaft; the hub is the rotor; magnets for clamping the stator coil windings are arranged in the hub; and the coil winding of the second stator is connected with the storage battery after being connected in series with the second control switch and the rectifying device. During braking, the controller controls the second control switch to be closed to charge the storage battery by using the electric energy generated by the coil winding of the second stator. The energy-saving hub motor can be applied to the wheels of electric cars.

Description

technical field [0001] The invention relates to a hub motor, in particular to an energy-saving hub motor. Background technique [0002] In recent years, with the increasingly prominent environmental and energy issues, motor vehicles, as the main source of urban air pollution and one of the main consumers of crude oil, are facing a technological revolution in energy conservation and emission reduction. With the increasing price of energy and the continuous tightening of national emission regulations, electric vehicles, as new energy vehicles, have become an irresistible trend in the development of the transportation industry now and in the future by virtue of their advantages such as energy saving and environmental protection. As the core component of electric vehicles, the performance of the motor directly affects the performance of the vehicle, and the drive of the wheels has evolved from the indirect drive wheels used in the past to the current direct drive wheels. As we ...
